Amazon Aurora is a hosted relational database service developed and offered by Amazon since October 2014.[1][2] Aurora is available as part of the Amazon Relational Database Service (RDS). Although it is a proprietary technology,[3] it offers MySQL compatible service since its release and PostgreSQL compatible since October 2017 [4] and it is also possible to stop and start Aurora Clusters since September 2018 [5]. Since August 2018 Amazon also offers a serverless version of AWS Aurora. [6]

Key features

Aurora does not require the user to provision database storage, as it automatically allocates storage in 10-gigabyte increments, as needed, up to a maximum of 64 terabytes.[7] Aurora offers automatic, six-way replication of those 10-gigabyte chunks across multiple locations for improved availability and fault-tolerance. Aurora also provides users with more comprehensive performance metrics, such as query throughput and latency, as compared to other RDS database engines.[8]

Compatibility limitations with MySQL

Amazon designed Aurora to be compatible with MySQL, meaning that tools for querying or managing MySQL databases (such as the mysql command-line client and the MySQL Workbench graphical user-interface) work with Amazon Aurora databases as well. Not all MySQL options and features are available, however: as of September  2016, Amazon Aurora is only compatible with one version of MySQL (5.6), and supports only InnoDB as a storage engine.[9]

Performance

Amazon claims fivefold performance improvements on benchmarking tests, due to "tightly integrating the database engine with an SSD-based virtualized storage layer purpose-built for database workloads, reducing writes to the storage system, minimizing lock contention and eliminating delays created by database process threads".[9] Other independent tests have shown that Aurora performs better than competing technologies on some, but not all, combinations of workload and instance type.[10]
